Minecraft version: 1.20.4
Modloader: Fabric
Environment: Multiplayer

Mod name: Villager Names

Is it possible to remove - somehow - all villager names given until now, or will they stay even when disabling the mod?

It's not possible to remove names automatically, since the mod basically gives the villagers a name tag. But I'll leave this open as a feature request to add a command for it. Appreciate the suggestion!
